Instead of using `.fail.cpp` tests, use `.verify.cpp` to check for the exact reason of the failure. In the case of deduction guides, use SFINAE based tests instead since that is our preferred way of testing those. Finally, ensure that we actually run the test in `iter_alloc_deduction.pass.cpp`, since we were not running anything before. Differential Revision: https://reviews.llvm.org/D123055
